Thank you for the response João. I will check

Hello. I've been away for a while in this hobby, and now I was thinking of picking it up again. I have 3 9x radios, one with upgraded chip aswell thanks to jhsa. One is fixed after a reverse polarity, as is why I found this great forum. And the last is in pieces for custom paint and stuff. All is mo...

Quite frankly I don't get this at all.. I'm all lost in all the short words.. XJT DHT DJT you name it.. but what I want i think is a XJT module.. but it's expensive.. and also i woul rather have it internally like the DHT module.. and i want the antenna to be stock as the 9X. no antenna in the back....

I like and recommend the external FrSky XJT module with FrSky X-Series telemetry and you can use it as a DJT module which uses D-Series sensors. The DHT has some limitations and you can install the XJT internally with modifications. See here for more info: (http://openrcforums.com/forum/viewtopic.p...

Mike.

Ok then.. it's back to plan B thanks for quick reply Mike

Hello. As mentioned erlier on this board I have had a lot of 9x's and done almost everything possibly wrong with them :) Including magic smoke and a chip replacement.. and also a chipupgrade to 128A :) Now i use the 9x with a 128A on it. But now i find this marvelous 9extreme board and it's everythi...

A great looking TX there mate :) Do you have a internal ftdi chip? so you can just plug usb into the tx? I was thinking, this is really much, so I have to start somewhere.. so i will surely buy some stripboard. And start with the tiny soldering, including telemetry, BT voicemod and so forth.. i will...

Thank you very much João. You've stuck in there with me and helped me alot on this matter and still when i fail and struggle and do stupid things to my TX you still encurage me to continue.. Thanks to you and others i got this working :) now i'm on to ordering parts for mayor upgrades :) i will foll...

Hello again. As time passes by I have a lot going on.. but every now and then i get the time to sit down and fiddle around with my toys. So here is an update on this thread... I have now successfully installed a new atmega128 in my TX, and flashed it with er9x 128 mod.. I'm so happy now, i was think...

Arduino UNO with sketch. Ive used it before when i jumpstarted a ocillator. .And writen many FW with it..

I have already tried to write Mike but not Now. . But the first i did was to write.

Ok.. one post missing. I tried the arduino Now and got "STK500 not in sync"

Is that one bad too? Let me see
Oh yes. That is the one with half the trace gone. . So there is contact but barely visual by eye..

jupp... i'm setting up my ardu for that now

The pin i've referred to as pin 19 is infact pin 35 after some inspection.. i said to start couting on the side towards crystal... now i checked the datasheets and found that it was pin 35.. and this goes out to nothing as I suspected since i can't find the traces... On the other hand, now i've trie...

Hmm i'm feeling quite out of it now.. but i don't find the "Read Fuses" option... am i overlooking something? can I use reset to factory or something?

EDIT: This could be my fault.. i need new EEPE

Ok.. I will try..Thank you once more

I suggest double checking every pin, of the processor, is soldered fully. Use a pin or a needle, and gently 'flick' each pin sideways. If it is not soldered, then it will move slightly and sound different to pins that are properly soldered. If you can flash successfully, then quite a lot is working...

Explaination to the picture.. If we look at the picture and call the most left pin on the crystal side of the chip for number one.. then i rippet trace 1, 3 and 19.. number one i got to just solder to the pad on the side, number three i'm a bit uncertain if the connection is all good, it is not comp...

MikeB wrote:What firmware did you flash?

Mike.

I flashed both with eepe and companion and ofc the 128 version. I can attach the hex later

Her is a pic

Will send when i get back home..☺

Forgot to mention. . When changing orientation on the chip i installed a brand new one.. So the one in the tx Now is solder ed only once and correct. And one more ting, this is another motherboard than the one i fried.. So this was working flawlessly before removing chip.. I was stupid enough to hav...

In the absence of replies im flooding the thread mysElf. The chip was mounted 180degrees wrong. New try gets to flash but No life.. ripped a trace with might be the cause. . Ideas?

I still want one... give me a pm on this matter mate

Ok.. after a Loooong wait it's finally done.. the chip is changed. I chose a atmega128A as my substitute.. no i've soldered in the chip but it seems like I have a short between Ground and Reset.. as I install the usbASP it disconnects from the computer.. and the led in the usbasp goes dark. I measur...

Thank you again Mike...

Thank you a lot mike.. then my next question is, what is the "AU" in the atmega2561 name? do i need specifficly this number? Atmega2561-16AU

Hmm, i don't seem to get a heads up when this thread is being replied to.. sorry for late response... So this the clue, is the 9x 8 or 16 mhz? and is there large differences between atmega2561 and the 128 one? someone please give me direct links so i don't get wrong pinouts and such? i'm bad at read...

this would od it then i guess?

@jhsa @mikeb you where talking about a atmege 128 chip witch would fit on my board, could you please guide me ti witch one?
